Radon Mitigation Systems Built for NEPA Homes

Keystone Radon Mitigation designs and installs radon reduction systems for homeowners and property owners throughout Northeastern Pennsylvania.

What Keystone does

Keystone Radon Mitigation is based in Throop, Pennsylvania and focuses on radon mitigation system design and installation. The work starts with the home, the foundation, and any radon results the homeowner already has.

Reviews the property layout and available radon results
Designs an appropriate radon-reduction system for the home
Installs the system with routing and fan placement selected for the property
Explains basic operation, system indicators, and practical maintenance
Advises the homeowner to arrange post-install testing to verify results

Keystone works from existing test results and mitigation needs. Homeowners should use an appropriate test method or qualified testing provider when a radon measurement is needed.

How Active Soil Depressurization Works

The most common residential mitigation approach creates suction below the foundation so radon is collected before it accumulates indoors.

1. Suction point

A suction point is created beneath the slab or relevant foundation area. Some homes need more than one suction point because of foundation layout or sub-slab conditions.

2. Sealed pipe

Sealed piping carries soil gas from beneath the home to the exterior discharge route. Accessible openings such as sump lids, cracks, or penetrations may be sealed where practical.

3. Continuous fan

An exterior or appropriately located fan creates continuous negative pressure. The system normally runs all the time so suction remains active.

4. Safe discharge

Radon is discharged above the occupied area where it can dilute outdoors, reducing the chance that soil gas is drawn back into the home.

What Installation May Involve

No two homes are identical. A mitigation plan may need to account for basement slabs, crawlspaces, sump pits, multiple foundation sections, pipe routing, fan placement, electrical requirements, sealing accessible openings, and the exterior appearance of the finished system.

Foundation conditions

Basement slabs, crawlspaces, block walls, additions, and separate foundation sections can affect suction point placement and pipe routing.

Sumps and openings

Sump pits, drains, cracks, and utility penetrations are reviewed because accessible openings may need sealing as part of the reduction strategy.

Fan and pipe location

Fan placement and exterior piping are selected around the home's structure, safety requirements, serviceability, and visual impact.

After Installation

A radon mitigation system normally runs continuously. A system indicator helps show whether suction is present, but it does not measure the home's radon level.

Arrange a post-mitigation radon test after the appropriate waiting period for the test method being used
Keep the post-install result with the home's records
Contact Keystone if the post-install result remains elevated
Contact Keystone if the system indicator changes or the fan begins making unusual noise

Maintenance basics

Check the system indicator, listen for unusual fan noise, keep discharge and intake components unobstructed, and retest periodically or after major structural changes. Fan replacement is a normal long-term maintenance item for active systems.

Radon Mitigation FAQs

Common questions from homeowners considering a radon reduction system.

How long does installation usually take?

Many residential installations are completed efficiently, but timing depends on the home, foundation layout, access, routing, and electrical needs. Keystone can discuss expected scope after reviewing the property.

Will the system be visible outside?

Many active systems include exterior piping and an exterior fan. Routing is planned around the home so the system can function properly while keeping appearance in mind.

Does the fan run all the time?

Yes. An active mitigation fan normally runs continuously so the system maintains suction below the foundation.

Is the fan loud?

A properly operating fan is usually not disruptive, but sound depends on fan location, mounting, and the home. Unusual new noise should be checked.

Can a home need more than one suction point?

Yes. Multiple slabs, additions, crawlspaces, or sub-slab conditions can require more than one suction point or a more detailed routing plan.

What does the system indicator measure?

The indicator shows whether suction is present in the mitigation piping. It does not measure the home's radon level, so a radon test is still needed to verify performance.

Who performs the post-install test?

The homeowner should arrange an appropriate post-mitigation radon test or use a qualified testing provider. Keystone advises customers to verify performance after installation.

What happens if the post-install result is still elevated?

Contact Keystone with the test result and test conditions. The system may need evaluation, adjustment, or additional mitigation work depending on the home.

Can Keystone evaluate an existing mitigation system?

Keystone can discuss existing systems and visible system concerns. The appropriate next step depends on the system design, indicator reading, fan operation, and current radon results.

Does mitigation affect resale?

A mitigation system and retained post-mitigation test result can help document that elevated radon was addressed. Sellers should keep test results and system information with home records.
